-#### Project building issue
-
-If you are facing strange errors with project compilation it could be a problem that after install of llvm clang if pointing to a default apple clang. You could check that with `clang --version`. It should not point to `/Library/Developer/CommandLineTools/usr/bin`, but something like `/usr/local/opt/llvm/bin`. So you should specify full paths to a compiler:
-1. Check full path with `brew info llvm`. Search for command that looks like
-```
-    echo 'export PATH="/usr/local/opt/llvm/bin:$PATH"' >> ~/.zshrc
-```
-2. Take bin path from it. In our case this is `/usr/local/opt/llvm/bin` It shouldn't differ for most cases.
-3. Append compiler to it and specify it in conan profile:
-```
-    conan profile update env.CC=/usr/local/opt/llvm/bin/clang clang && \
-    conan profile update env.CXX=/usr/local/opt/llvm/bin/clang++ clang
-```
-4. Specify compiler with full path to cmake:
-```
-cmake -DCMAKE_BUILD_TYPE=Release -DCMAKE_C_COMPILER=/usr/local/opt/llvm/bin/clang -DCMAKE_CXX_COMPILER=/usr/local/opt/llvm/bin/clang++ ../
-```
-5. After successfull finish of that command processing compile project with:
-```
-make -j$(nproc)
